Tombstone (Belated)Tuesday--Buried Stones

Some of the stones of my Gilberts are large and very easily read.  Such as this stone at the end of my row of two Great-Great-Grandparents, two Great-Grandparents and a great aunt.  It looks pretty plain, doesn't it?

However, while most stones in the cemetery face east or west, this faces north, toward a bush and tree.  It is very difficult to find at times.   Last time I was there I know I was unable to pinpoint it.  (You would think that turquoise shed in the background would make it easy to locate, wouldn't you?)
But the row of stones behind it look like this.

Great-Grandpa Roy's stone is typical of the row.  On this visit, I wiped it off as best I could, but the sod was encroaching upon it. 

On another visit the same stone was more readable.  I usually go by there at least once a year, now that I know where they are.  I or someone had cleared the sod away and even revealed the smooth pink granite border.  All five stones are the same size, style, and, alas, set flush to the ground.  The stone of the great aunt gets tended by her son, last I knew.  But he is now in his 90's, the care and cleaning may fall to me.
I better get up there soon.  Last year I didn't have time to hunt and couldn't locate them.
